We have  a broken DECStation 3100 that refuses to reboot.  I do not know
how the problem started, but today the machine couldn't do xwindow logins,
only console.  So I rebooted it.  However, the power-up check couldn't
find SCSI 3, and hence the entire machine is DEAD.  Please come and
fix it.

Name:		Samsara.mit.edu
Type:		DECSTation 3100
Location:	48-209 MIT
Contact:	Lynn B. Reid or anyone at x3-5484
Phone:		x3-5484

Problem:  On reboot, here are the symptoms:

KNO1 V7.03
7..6..5..4..
??                <-- remains flashing

I hit control C and then typed:
>>boot
The disk makes a noise like it is spinning up after the machine
says that bit about booting from rz(0,3,0)vmunix, and then these
errors occur:

Excptn:	<vtr=NRML>
Excptn pc:	0x806000024
Creg:		0x3000000c<CE=3,EXC=WMISS>
Sreg:		0x30080000<CU1,CU0,CM,IPL=8>
blah blah blah.....


Thanks!
